t7700-repack: add two new tests demonstrating repacking flaws
1) The new --kept-pack-only mechansim of rev-list/pack-objects has replaced --unpacked=. This new mechansim does not operate solely on "local" packs now. The result is that objects residing in an alternate pack which has a .keep file will not be repacked with repack -a. This flaw is only apparent when a commit object is the one residing in an alternate kept pack. 2) The 'repack unpacked objects' and 'loosen unpacked objects' mechanisms of pack-objects, i.e. --keep-unreachable and --unpack-unreachable, now do not operate solely on local packs. The --keep-unreachable option no longer has any callers, but --unpack-unreachable is used when repack is called with '-A -d' and the local repo has existing packs. In this case, objects residing in alternate, not-kept packs will be loosened, and then immediately deleted by repack's call to prune-packed. The test must manually call pack-objects to avoid the call to prune-packed that is made by repack when -d is used.
